Sarah’s stunning piece is formed with 562 reused bottle ends, each one hand cut and attached to each other gradually building into a spherical shape. Each bottle end holds a LED inside, which also connects to Twitter. When certain words were tweeted, such as “recycling” and “ocean”, the Twitter Ball flashes in different colors.

As part of the installation, the lamp was recently streamed live in action so that visitors to the website could view the tweet-reactions happening. But beyond a flurry a lights, each time a message was re-tweeted, $1 was donated to the research foundation.
